High Power Filter Wavelength Division Multiplexer
980/1060nm
Filter Wavelength Division Multiplexing (FWDM) is a device for optical wavelength management. It utilizes proven ultra-low-loss thin-film filter (TFF) technology and proprietary design of non-flux metal bonding micro optics packaging. High Power FWDM features High Power Handling Capability, high reliability, high extensibility, high channel isolation, epoxy free optical path, simultaneous transmission of multi-wavelength. It’s been used for fiber lasers, fiber amplifier, optical sensors and lab research.
